How can we use an industrial waste to make a product with a local function?

Marble Chalk, is a product that uses an industrial waste material to fullfill a sustainable and local function, in the context of South Tyrol. This is a set of liquid and powder climbing chalks that are 2/3 made from marble powder residues. The liquid chalk is for the first application onto the hands, and before it dries, it seeps into every porous crack, to create a really thick and grippy base layer so that climbers can get their crimp on. My goal was to use the wasted luxury dust from the sawing processess of Lasa Marmo (the stone quarry), in order to make a product with a local application, which in this case are the Dolomites, the headquarter of the worlds most elite climbers. The starter kit of the marble chalk includes, a 250ml bottle of liquid chalk and a 500g bag of powder chalk. The powder chalk can be filled into a chalk ball/bag and can be taken up the rock climbing wall to chalk up the hands while hanging. These two packages are held together by a silikon ring and a carabiner so that it can be hung up in a store. The silikon ring also fits over the 400ml bottle which can be bought seperatly, like the 1500g chalk bag. This silikon ring is intended for carrying, and gives the user the possibility to hang both sizes of liquid chalk on their climbing gear.
